Hello and thanks for using this service, if you have been waiting do not worry or get upset. I am HVAC Guru an extremely experienced tech on the site and I try to get to as many customers as I can. I just picked up your question now. NOTE it takes time for me to type research and add links so please wait for me to respond back I can only do this so fast. Secondly I am not paid anything until you rate my service good using the STAR RATING LINK at the top of your page, the money is paid to the site not me directly. Answer: That is typically due to bad batteries or a blown fuse in the furnace, there is a low voltage fuse in the furnace on the control board that may have popped. It is typically a 3-5 amp SLOT or BUS fuse right on the board itself. Check that and see if you do not have batteries. All I ask is please use the Star Rating Link at the top of your page before leaving, that is the only way I am paid anything through the site.....tips are greatly appreciated so thank you very much for using this service. If you have any other questions just post back to me here anytime!

Hi there,I was just touching base with you because I have not heard back from you and the question is still open and unrated, if there is something else I can help you with follow up questions are free and can still be handled even after you rate the answer or did you just forget to rate the answer?
